    Description / Table of Contents: Synthesis of 1,1′-Bicyclobutyl and 1,1′-Bicyclohexyl DerivativesDimeric glycols (2, 3 and 20, 24) are prepared from ethyl 3-oxocyclobutanecarboxylate (1) and 4-substituted cyclohexanone derivatives 9, 10, 23 by low valent titanium reagents. Dimeric olefins (17, 18) were obtained from the cyclohexanones by Barton's thiadiazoline method. Some experiences with cis-protecting groups for the 1,1′-dihydroxy dimers are presented.
    Notes: Aus dem 3-Oxocyclobutancarbonsäure-ethylester (1) und 4-substituierten Cyclohexanonen 9, 10, 23 werden mit niederwertigem Titan die dimeren Glycole 2, 3 bzw. 20, 24 hergestellt, aus den Cyclonexanonen mit Bartons Thiadiazolin-Methode auch die dimeren Olefine 17, 18. Einige Erfahrungen mit den Schutzgruppen zur cis-Fixierung der 1,1′-Dihydroxy-Dimeren werden mitgeteilt.
